A rectangular piece is 20m long and 15m wide.from its four corners quardrants of radii 3.5 have been cut.find tge area of the remaining part
Answered by admin @
Consider first the size of the original rectangle: it is 20x15=300 square meters.
Now consider the piece removed.
The four quadrants make a circle with area pi*(3.5*3.5).
That is about 38.5. Subtract this from the are of the rectangle, 300, and you get 261.5 square meters.
